城市轨道交通钢混组合结构高架车站抗震设计关键技术研究

Research on Key Technology of Seismic Design for Elevated Station with Steel-concrete Composite Structure in Urban Rail Transit

文中以长沙市轨道交通某路中岛式钢-混凝土混组合结构高架车站为背景,基于整体建模和结构性能化设计理念,研究了高架车站结构在地震作用下的结构整体受力性状、位移变形及墩柱和构件的延性比等关键指标,得出钢-混凝土组合结构高架车站具有优异的抗震性能的结论。

Based on the concept of overall modeling and structural performance-based design, this paper studies the key indicators of the overall structural behavior, displacement deformation, ductility ratio of piers and components of the elevated station structure under earthquake action, taking an island type steel concrete composite structure elevated station in Changsha rail transit as the background, and concludes that the steel concrete composite structure elevated station has excellent seismic performance.
